Sounds like over threshing problem to me,,,slow down the cylinder,,,,and_or open concave,,,,I've been told to run as low as 250 in beans,,,never done them myself. but if they are real dry you have to run that low,,,if not do them in the morning and evening when the dew is on.

Start with your cylinder around 400, open your precleaner just enough to let beans through, and about same on the chaffer. Close cylinder most of the way, 2-3 works for me.. Play with the fan, but start around 1100 and watch the sample in the tank. Your sample should be able to grade less than 1% total fm including splits. gs
